I tried using one in my room when I worked in a mining camp up north. I wanted to kill the odor of old tobacco smoke left in the room from the previous tenant. It did that but was overpowering, I couldn't sleep in the room until it was aired out. I haven't used one since.

Some recommend baking soda to absorb odors and it does to some extent. I mix in some with the kitty litter for my cat and that seems to control that odor. I've read that a canister of charcoal absorbs room odors better than soda but I've never tried it.
